History

The first record for the region came in 1951 when one was caught at Tynron (VC72) on 28th August (Duncan & Cunningham 1952). From 1974-79 it was caught annually at the Gatehouse-of-Fleet Rothamsted station, these being the first records for Kirkcudbrightshire (VC73). The first for Wigtownshire (VC74) was at Aird in 1975.

In July 1982 at the Scottish Entomologists' meeting at Barony College (VC72) it was trapped again, but it was 1990 before another was found in Wigtownshire, when it was found at Portpatrick in August. Further records followed from 1995-2006 from Glendow, Powfoot, Kirkton and Caerlaverock WWT (all VC72) and Meikle Kirkland, Auchencairn, Edingham and Abbey Burn Foot (VC73).

Identification

The small blackish dashes with fine arrowheads close by to the outer edge of the large broad forewing should aid identification.
